Ball bearing units for high-temperature applications

Except for the cage and seals, SKF Y-bearings for high-temperature applications correspond in design to standard Y-bearings in the YAR 2-2F series. The bearings have a shield and flinger on both sides to prevent solid contaminants from entering the bearing.

The entire bearing and shield surfaces are manganese-phosphate treated to increase lubricant adhesion to the metal and improve bearing running properties.

The radial internal clearance is a multiple of C5 to prevent the bearings from seizing, even when they cool down rapidly.

Benefits and features of high-temperature insert bearings and ball bearing units include:

• No relubrication required
• All variants are lubricated for the life of the bearing with graphite-based high-temperature lubricants.
• Simple replacement
• Boundary dimensions are the same as for standard bearings and units.
• Operating temperature up to 350 °C (660 °F)
• Radial internal clearance and lubricant are optimized for high-temperature operation.
• Quick and easy mounting and dismounting
• No painting required
• The housing is coated with a high-temperature-resistant coating.
